Application filed December 17, 1918. Serial No. 267,143.

This invention relates to heaters for use in connection with silos. It is well known that ensilage, especially when stored in a single wall silo, will freeze next to the wall to a depth sometimes amounting to two or three feet and as it is not desirable to feed frozen ensilage to stock and it is, furthermore, very difiicult to remove the ensilage when frozen, it is an object of the present invention to provide a heater that can be supported within the silo where it will thoroughly heat the ensilage so that it will not freeze.

Another object is to provide a heater that can be combined readily with a silo and that can be lowered within the silo as the ensilage is removed.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a vertical section through a silo and the heater therein.

Fig. 2 is a section on line 2'2, Fig. 1.

Fig. 3 is an enlarged section through a portion of the periphery of the cover.

Fig. 4 is a plan view of the structure shown in Fig. 3.

Referring to the figures by characters of reference, 1 designates a series of arcuate rods connected by coupling sleeves 2 to form a ring and this ring has rods 3 extending inwardly therefrom to a small center ring 4. Bails 5 are extended upwardly from the ring a and connected to tackle indicated at from the ring 4 are rods 7 the lower ends of which are connected to eyes 8 at the upper ends of U-shapedhangers 9. These hangers support a stove of any desired construction, as shown at 10 and which has a smoke. outlet from which extends a smoke pipe 11. A covering of fireproofed canvas or like material is supported on the ring 1-1 and rods 3 and is connected to said ring by spring clips, said covering being shown at 12 and the clamps at 13. A seg mental plate 14 is mounted on two of the rods and has an opening through which the pipe 11 extends.

In using the heater a hollow is formed in the top of the ensilage and the tackle 6 is connected to the top of the silo. A fire is built in the stove and said stove lowered into the hollow. This will warm the ensilage and prevent it from freezing and the cover 12 will retain the heat. By pulling the heater upwardly access can be had readily thereto for supplying fuel thereto at a point above the level of the ensilage.

While the heater can be used as described for preventing ensilage from freezing, it will also be found useful in thawing ensilage that has been frozen. By forming a recess in the frozen ensilage and lowering the heater thereinto the material will soon be thawed and can be fed out readily to the stock. 7

What is claimed is A heater for silos including arcuate rods,

connections between the ends of the rods, said rods and connections forming an outer ring, an inner ring, radial rods connecting the inner and outer rings, a stove suspended from the inner ring, supporting means connected to the inner ring, an apertured plate secured to certain of the radial rods, a smoke pipe extending through said plate and from the stove, and-a cover mounted on the radial rods and connected with the outer ring and the inner ring, said inner ring forming an opening for supplying air downwardly to the stove to support combustion.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signa ture in the presence of two witnesses.

ANDREW J. JOHNSON.
